GRAND RAPIDS, Mich. (AP) — An inmate in Michigan’s Upper Peninsula has filed a lawsuit saying the quality of food served by a prison food contractor isn’t satisfactory.

The Grand Rapids Press reports the lawsuit by Christopher Velthuysen is in U.S. District Court in Grand Rapids. The 43-year-old is behind bars on a life sentence at Baraga Correctional Facility and has filed past unrelated, unsuccessful lawsuits.

The lawsuit says spoiled food was served and menus didn’t match what was on the plate.

The Michigan Department of Corrections and Philadelphia-based Aramark Correctional Services aren’t commenting on specifics, citing the pending litigation. But Aramark spokeswoman Karen Cutler says menus are designed to meet established nutritional requirements.

Aramark’ work has been under scrutiny. Michigan fined the company $200,000 last month and there’s an independent monitor in place.
